Product Description
The 6303-ZZ is a 17mm single row radial ball bearing that’s shielded with metal on both sides and pre-lubricated with bearing grease. It’s a 47mm OD shielded ball bearing 6303Z made of chrome steel and features deep groove geometry that’s perfect for high speeds and heavy radial and axial loads. Rolling bearings like 303KDD use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed and Shielded bearings are lubricated with oil or grease in the bearing factory, while open bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan.
6303ZZ is used in a range of applications from agricultural machinery to conveying equipment, electric motors, CNC machinery, trucks, mining equipment, train, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, motorcycles, household appliances, power tools and machines, gear boxes, and among others.
Usage: Electric Motor, Fan, Power Tools, Conveyor Bearing, Pilot Bearing, Casters Bearing, Dolly Wheel Bearing, Alternator, Gear Box, Tension Pulley, Wheel Bearing and much more.
